What preparations need to be made before the door head display is adjusted point by point?

Abstract: Clean the touch display, remove dust and stains on the lamp surface and mask, and avoid its impact on brightness. If you need to replace the mask, please ensure that the color of the mask is the same as before, otherwise the display will be affected, especially in the daytime, and the improvement will not be much after correction; 　　 1. Clean the touch display, remove the dust and stains on the lamp surface and the mask, and avoid it The effect of brightness. If you need to replace the mask, please ensure that the color of the mask is the same as before, otherwise the display will be affected, especially in the daytime, and the improvement will not be much after correction; [Door display]　　2. Replace poorly functioning modules: some lights do not light up , There are too many dead lights, the scanning is not normal, the overall light is too dark (the resistance may be wrong), the cable or the socket problem affects the display, etc. Make sure that the final display, scanning, and picture are normal, and there is no phenomenon such as too dark, constant light, continuous light, etc.; 　　 3. Receiving card upgrade: If the currently used receiving card does not support correction or the loading points are not enough, it needs to be upgraded. Due to the risk of dead cards in the receiving card upgrade, the customer needs to contact the control system company in advance for upgrade and related processing; 　　 reminder: brightness correction only improves the uniformity of the full-screen display by reducing the brightness of some lights or improves the actual problems caused by inconsistent brightness. Can not increase the brightness of the lamp, can not change the angle of light, can not correct other display problems caused by hardware function problems (power supply, resistance, cable). The calibration collection needs to be carried out in an environment without wind, rain and fog interference, so the customer needs to arrange the calibration time according to the local weather environment, or take relevant measures to ensure that the collection equipment collects accurate data in a non-interference environment as much as possible, and finally achieves the best Good correction effect. There is something to do before point-by-point calibration, and after point-by-point calibration, you can’t save trouble: After the point-by-point calibration is completed, the follow-up maintenance of the display faces new problems, such as replacing the receiving card, updating the data after replacing the module, and the target brightness of the display. And color gamut adjustment, etc., these should not be forgotten! 【Traffic Guidance Display】
